I disagree that this is an external bug.

fossil could/should execute the /bin/sh command as its command to execute on the remote side because fossil is requiring a particular shell, in this case, sh.

Or, if that's not possible, have it fire off an 'exec bin/sh' as its first command upon establishing an ssh connection. Something like (one of the two options should work - dry coded, unfortunately):
